Swallowtail butterfly’s (Papilionidae) family is a large group including at least 550 species in the world, one of the most evolved butterfly families, and selects many special plants as a host plant. Many scientists have studied on the mechanism for host selection by swallowtail butterflies and many results including attractant, ovipositional stimulant, and feeding stimulant in each host plant have been reported. However, most of the reports are related to Papilinonini and Troidini genus and not to Graphiini genus. The reason why there are few reports about this genus is based on their nature. That is, this genus butterflies, especially common bluebottle, Graphium sarpedon, are very nerves and rearing for successive generations is difficult in the laboratory, emergence-adult never laid their eggs on the host plant and so on. We, therefore, have tried to isolation and identification of attractant, feeding stimulant, and ovipositional stimulant in the camphor tree to the common bluebottle, G. sarpedon.
